[SR-Users] How to access rtpengine rtcp-metrics?

Hi all I'm trying to incorporate rtcp data from rtpengine into our CDRS. So trying with the first interesting value, the average mos. modparam("rtpengine", "mos_average_pv", "$avp(mos_average)") If I understood right, to get this variable set, I need to call rtpengine_manage() on the message that terminates the call. So on an established call, that is either BYE or the 200 OK to the BYE. Right? if ($rm == "BYE") { rtpengine_manage(); xlog("L_INFO", "$cfg(route): $rm: MOSS: $avp(mos_average)\n"); } onreply_route[MANAGE_REPLY] { [...] rtpengine_manage(); xlog("L_INFO", "$cfg(route): $rm reply MOS: $avp(mos_average)\n"); } Messages pass those blocks, $avp(mos_average) is 'null' no mater what. What am I missing? In the syslog output of rtpengine I see there is rtcp data.
